  Usage: git curate [options]

  Interactively step through the local branches of the current git repository, showing various
  information and asking whether to keep or delete each branch.

  In the default (interactive) mode, the current branch is excluded, as it cannot be deleted.

  Note git-curate does not perform a "git fetch"; if you want to be sure the output reflects the current
  state of any remotes, run "git fetch" first.

  Options:
  EOF

    opts.on(
      "-l",
      "--list",
      "Show summary of local branches, including current branch, without stepping through interactively"
    ) do
      self.parsed_options[:list] = true
    end

    opts.on(
      "--merged",
      "Only list branches whose tips are reachable from HEAD",
    ) do
      self.parsed_options[:merged_opt] = "--merged"
    end

    opts.on(
      "--no-merged",
      "Only list branches whose tips are not reachable from HEAD",
    ) do
      self.parsed_options[:merged_opt] = "--no-merged"
    end

    opts.on("-h", "Print this help message") do
      puts opts
      return false
    end

    opts.on("-v", "--version", "Print the currently installed version of this program") do
      puts "git curate v#{GitCurate::VERSION} #{GitCurate::COPYRIGHT}"
      return false
